Not the person you're responding to, but as soon as I read stuff like "I trained tiny network" I tend to imagine Russian. It's the missing "a". Same thing happens in "I'm speaking with heavy accent".
I'm not a native speaker but my inner voice also switched to Russian accent very quickly!
Missing articles in English is the usual give away for someone with a slavic native language such as Russian.
I'm native Hungarian speaker, and the giveaway is the exact opposite: more definitive articles than it should be. We use that way more often in Hungarian than in English, and we are really bad with it.
Missed opportunity of intentionally introducing a few extra in this comment
